LOCKING DEVICE FOR BALlNG-CHAMBERS- SPECIFICATION forming part of Letters Patent No. 792,937, dated June 20, 1965.

Applicatioufiled August 29, 1904" Serial No. 222,596.

To mZZ whom, it rnag concern.-

Be it known that I, HARVEY DANIEL SMITH, of Battlecreck, in the county of Calhoun and State of Michigan, have invented certain new and useful Improvements in Looking Devices for Baling-Chambers; and I hereby declare that the following is avfull, clear, and exact description thereof, reference being had to the accompanying drawings, which form part of this specification.

This invention relates to baling machines or presses, and is an improved door closing and locking device especially designed for locking the doors of the baling-chambers in a simple and powerful manner.

The invention may be used in connection with other swinging doors which are desired to be held securely. In particular the invention is intended to be used with the balingchamber shown in myapplication for patent Serial No. 1953,8 33, filed February 29, 1904, which application discloses a baling-chamber having swinging or movable walls and bottom and a swinging door adapted to move the Walls and bottom of the chamber into closed position and hold them thus until the door is released. This requires a positive and secure mechanism for closing and retaining the door in closed position, and such device is the subject of my present invention.

I will describe the invention in connection with the accompanying drawings, the parts for which protection is desired hereby being summarized in the claims.

In said drawings, Figure 1 is an enlarged transverse sectional View through the outer end of a baling-chamber, showing the door and my improved door closing and locking devices. Fig. 2 is an end elevation of Fig. 1.

The door F may be of any suitable form and is preferably hinged on rod f, which is attached and supported between the upper and lower bars attached to the frame-supports of the baling-chamber.

B B designate the opposite swinging walls of the baling-chamber, and B the bottom of said chamber, these parts being only partially shown in the drawings, as they form no essential part of the present invention.

As shown, the door is strengthened at top and bottom by metal bars F. It is provided on its hinged end and inner face with cams ,7', and on its free end and inner face with other cams J and at its bottom or lower edge with cams K. The cams J are adapted to engage the opposite side walls B of the baling-charnber and force the same into closed position as the door is closed, and the cams K are adapted to engage the bottom B and raise the same into closed position as the door is closed, all

substantially as described in my aforesaid application. At the side opposite the rod f is a vertical rod 9, on which is pivoted a bifurcated bail G, which is provided on its upper and lower ends with cams G, which are so shaped that when the bail or lever G is swung outwardly in the position shown in dotted lines in Figs. 1 and 2, the door F can swing open; but after the door is nearly closed by forcibly turningthe bailGaround toward the side of the baling-chamber cams Gr engage the adjacent edges of the door (as shown they engage ends of the top and bottom angle-irons F of the door) and forcibly close it, so as to cause it to draw the sides and bottom into position and hold them in such position as long as the bail is in the position shown in full lines in the drawings. The pressure of the edges of the door against the cams Gr when the parts are in this position will only tend to lock the bail G and door in closed position, as Will be obvious from an inspection of Fig. I. This construction affords a very simple and powerful door closing and locking device. The bail Gr is thrown into locking position by simply swinging its handle 9 around toward the side of the bailing-chamber, and it is released by simply swinging the bail-handle away from the baling-chamber. The cams Gr terminate at G so as to permit the door to open readily .90 and clear the cams when the bail is swung doors within the scope of the invention, and I do not wish to restrict myself exclusively to its use in connection with a baling-chamber of the character described.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In combination with a swinging door, of a door closing and locking cam pivoted at the side of the door-opening opposite the hinge and adapted when turned in one direction to engage the outer or free end of the door when the latter is nearly closed and to forcibly close the door and hold it closed until the cam is turned back, substantially as described.

2. In combination with a baling-chamber having a swinging end door; a door closing and locking cam pivoted at the side of the door-opening opposite the hinge and adapted when turned in one direction to engage the swinging free end of the door when the latter is nearly closed and forcibly close it and hold it closed until said cam is turned back.

3. The combination of a door hinged at one side, a bail, hinged at the side of the door-opening opposite the door-hinge, provided With cams on its ends adapted to engage the free end of the door as the latter is closed, said cams being so shaped that when the bail is swung outward the door can be opened, and

when the bail is swung inward the cams will engage the free end of the door, forcibly close the latter and lock it by reason of the pressure exerted by the edge of the door against the cams.

4. In a baling-chamber, the combination of movable or hinged side Walls, an end door having cams on its sides adapted to respectively engage the outer ends of the side walls of the chamber and move them inward, With cams Gr adapted to engage the free end of the door and forcibly close and lock the same, substantially as described.

5. The combination of a baling-chamber having hinged side Walls and bottom, and a swinging end door having cams on its sides and bottom edges adapted to respectively ongage the outer free ends of the sides and bottom of the chamber and move the same inward; with means for fastening said door, consisting of a bail G having cams Gr on its ends adapted to engage the free end of the door and forcibly close and lock the same.

In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses.
